2 Claims.

Our invention relates to air conditioning apparatus for railway vehicles.

It is an object of our invention to provide an air conditioning apparatus for railway vehicles, in which there is a combination of the advantages of an articulated truck beneath the adjacent ends of adjacent car bodies, the advantages of a separable truck for the respective ends of the adjacent car bodies and the advantage of an air 1()y .conditioning unit being carried on the end of each car body adjacent the end of the adjacent car body, so that the air conditioning unit can be carried in the space between the two adjacent car bodies. l5 It is an object of this invention to provide in this combination a detachable v estibule which is detachably supported by one car body in overlapping engagement therewith and, when this car body is assembled with the adjacent car -body 20?' and the separable trucks are connected to form a single truck, then the air conditioning units supported on the respective faces of the respective ends of the respective car bodies will be enclosed in the space between the vestibules. 25' It is our particular object to provide a distribution system for conditioning the interior oi a railway vehicle in associationwith the detachable air conditioning unit mounted on the end of the vehicle in space that is customarily lost space, as `it is the area between the ends of the vehicle that is necessary for the relative movement of the two vehicles with respect to one another upon the common truck which supports these ends. `An important object of this invention is that vthe air conditioning apparatus is all located in a removable cabinet. In case of failure of this equipment the cabinet is just replaced by another cabinet unit. The work of repairing the equipment in the cabinet can be done in theshop at a saving of time and costs. The work does not have'to be done on the tracks or in ltrain sheds in all kinds of weather. The vehicle can be kept in regular service with no loss of .time or laid-up equipment due to air conditioning apparatus.

This application is a division of our application. Serial No. 99,'996, led Sept. 9, 1936.

Referring to the drawings:

Figure l showsthe adjacent ends of adjacent car bodies connected together and their respective trucks connected together to form a single truck to serve as a support for the articulation of the two car bodies on the common truck. The air distributed ducts and air conditioning units are shown in vdotted lines. 56A Figure 2 is a similar view withthe car bodies separated, showing the independent support of the ca'r bodies by the separable trucks and the independent support of the air conditioning units by the respective car bodies.

Figure 3 is a top plan view, partially in section,

showing the arrangement of the accordion vestibule, the vestibulevdrum, the yielding supportsA therefor and air conditioning units.

Figure 4 is an end elevation of the car body which has a truck that supports the cylindrical vestibule. 'I'his view also illustrates the support of this car body. v

Figure 5 is a detail view of the interior of this air conditioning unit.

Figure 6 is asection on the line 6-6 of Figure 4. I

Figure 7 is a rear elevation of the air conditioning cabinet.

Figure 8 is an elevation of one end of a car body with the air conditioning cabinet removed showing the panel construction permitting access from the inside of the car to the air conditioning cabinet.

Referring to the drawings in detail, I designates a car body and 2 an adjacent car body. These car bodies are mounted upon a common truck consisting of the halves, generally desighated 3 and 4`. These halves are joined together by the anchoring pins 5` and aligning studs 6 and sockets 1 arranged on the adjacent frame meme bers 8 and 9. Each truck half is provided with a rear wheel III which can be raised and lowered at will, as is more fully set forth in the application of David M. Ritchie Serial No. 7,752 led Feb. 23, 1935, and now Patent No. 2,111,676, dated March 22, 1938, which also describes completely this truck and the method of support of the 4cylindrical vestibule hereinafter described.

The wheel I0 is only lowered when the halves of the truck are separated, as in Figure 2. In addition to the wheels I 0 with their axle, there are the main wheels I I having an axle I2. A pair of transverse bolster springs I3 yieldingly support the bolster I4 which carries side bearings I5 eny gaging the sidebearings I6 on the opposite sides of the bottom of the car frame I'I. 'I'he inner ends of these springs I 3 rest upon pads I8 mounted upon the frame of the truck. 'I'he outer ends of these springs are supported upon swinging links I9 pivoted upon the truck frame 20. 'I'he center portions of the springs I3 support the opposite ends of the bolster I4.

This bolster carries a socket casting 22 which p is equipped `with a pin 6a and a'socket 'la for cooperatively engaging with similar mechanism on the adjacent truck half; The casting 22 is provided with a ball 24 associated with the sockel'I 25 that is carried on 'the bracket 26 on the end of thecar frame I1.` Within the ball 24, there is mounted Within a socket 21 upon a ball 28, the supporting pin 29 for the bottom 30-of the cylindrical vestibule 3| This vestibule is arranged in overlapping relationship to the car frame l1 and theiloor that it supports. It is maintained in its substantially vertical position by a plurality of oppositely disposed spaced spring pressed rollers 32 which are carried in roller supports 33 that are impelled towards the vestibule by the springs 34 mounted within the socket or cage 35 inthe end of the frame 36 constituting a part of the door structure of the car. This frame 36 of the car is engaged with a yielding, sealing strip 31 carried on the vestibule 3|.

The cylindrical vestibule has cut-away door portions 3|a to permit the passage of passengers therethrough from car to car. Each car is provided with a door 36 mounted in the frame 36.

'I'he top of the vestibule is held in position by the following mechanism. There is mounted on top of the vestibule cover 39 a bracket 40 which has oppositely disposed eyes 4|. 'I'hese eyes are connected to piston rods 42 having pistons 43 Working in the cylinders 44. There are springs 45 on either side of the piston 43. The cylinder 44 is connected by a staple 46, corresponding to a staple 41 mounted on the pad 48 which is in turn mounted upon the car body face. This vestibule is yieldingly held in its vertical position despite the swinging movements of the car bodies on the articulation and the vertical movements due to brakes in grade.

The adjacent car bodies have connected on their ends the collapsible accordion vestibules 49, the outer ends of which are connected to the arcuate frame member 58 that is supported at its bottom by the car frame members I1.

'I'his leaves a space between the adjacent end walls and 52 o f the adjacent car bodies, the accordian vestibules 49 and the vertical side wall 3| of the vestibule drum. This space is partially occupied by the detachable air conditioning cabinets 53 which are supported (see Figure 4) by lugs 54 in` socket brackets 55 bolted on the face of the end sill casting or iloor frame I1 of the car body. The top of this cabinet is connected by straps- 56, removable bolts 51 and ears 58 on the car body face 5| or 52. By removing the bolts 51 and lifting the cabinet 53, it is possible to completely remove the entire air conditioning apparatus for service, replacement or repair, without putting' the train out of permanent commission, while the servicing or repairing is being carried out. 'I'he top of the cabinet is detachably connected to a discharge vent passageway 59 which communicates with the discharge passageway 69 in the top of the car to'which the air conditioning cabinet 53 is attached.

Thereturn air returns through the passageway 8| to the bottom of the cabinet. Fresh in'- is used as a cooling coil, o ver the heat tempering coil or radiator 61, thence upwardly through the fan 68 in the casing 69 and thence out through the discharge passageways 59 and 69. The

spectively as supply and return pipes connected 'A to the steam system of the train.

Within the cabinet 53 is a separate compressor compartment 15, in which is mounted the compressor 16, its driving motor 11 and a fan 18 which draws in air through the opening 19 in the face of the cabinet 53. This air is discharged through the exit grill 11a adjacent the top of the compressor. 'I'he condenser 18a is in open communication with the exterior of the cabinet 53 and is enclosed within its own casing 19a. It is thus in a position to be cooled in the usual manner.

In operation, the adjacent cars, when coupled Y together, act as any other articulated train would act. To all intents and purposes., it isa solid articulated train. The dilculty with articulated trains has been that being a complete unit of a series of car bodies, if anything happened to the apparatus of any one of the car bodies, it placed the entire train out of commission. By the present invention, it is possible to' separate the bodies independently, one of the otherwith ini dependent trucks and to remove one of the bodies veniently done than attempt to perform the same service upon the air conditioning equipment while on the train.

We have provided the usual jump-over connections, as indicated, on the jump-over engaging plate 80.

'I'he air conditioning cabinet is optionally provided with a series of removable back panels 8|, 82, 83, 84, 85 and 96. These panels are directly behind corresponding panels in the end of'the car body as at 81, 88, 89 and 90. Thus, if individual pieces of equipment are to be adjusted or removed, the opening of the panels 91 to 90 inside of the car will enable access to the panels 8l to 86 in the back of the cabinet. This can vbe done without going between the car bodies or removing the cabinet from its position on the car body. v

' The front of the cabinet is provided with access doors 9|,J 92, 93 and 94.

It will be understood that we desire to comprehend within our invention such modifications as come within the scope ofthe claims and the invention.

Having thus fully described our invention, what we claim as new and desire to secure by Letters Patent is:

l. In an articulated railway train, the combinaton of adjacent cars, a common truck, means for articulating said cars with respect to said truck, an enclosure for the space between said cars, mounted on the .side walls of the cars, a vestibule located between said car bodies, and an air conditioning unit operatively connectedwith a distribution system in the car body to which itl is attached mounted on the outside end of the car body between said vestibule and said enclosure enclosing the articulation.

2. In an articulated railway train, the combination of adjacent cars, a `common truck, means for articulating said cars with respect to said truck, an enclosure for the space between said cars mounted on the side walls of the cars, a vestibule located between said car bodies, and an air conditioning unit operatively connected with a. distribution system in the car body to which it is attached mounted on the outside end of the car body between said vestibule and said enclosure enclosing thev articulation, said air conditioning cabinet being vertically disposed on the end of said car body and of such horizontal dimensionas to permit said bodies to approach one another on the articulation without the air conditioning unit engaging the opposite wall of the opposite car body.
